The Service Employees International Union said Tuesday it is putting more than $1 million behind advertising aimed at supporting lawmakers’ efforts to overhaul U.S. immigration laws.

The union said it plans to spend in the seven figures on a national ad campaign to support immigration legislation now being debated in the Senate, though it wouldn’t be more specific about the amount.

The campaign’s five commercials will start airing on Tuesday through the end of June, running in rotation on national cable networks including CNN, MSNBC, and ESPN. The ads will also air on major television networks including NBC, CBS, FOX and ABC during the Sunday morning political shows.

“We’re seeing a growing consensus across the country that we need to get immigration reform done and get it done now,” said SEIU President Mary Kay Henry. “These ads show the breadth of support for commonsense immigration reform and highlight the diverse voices that are integral to moving this debate forward,” she added.

The ads feature everyone from war veterans and law enforcement officials to small business owners and Republican voters. One 30-second ad called “Now” features two Republican voters who, like many Democrats, say the immigration system is broken. “Congress needs to grow up, stop fighting with each other and work together … you can’t deport 11 million people … this has to be fixed now, not 10 years from now,” one woman in the ad says.

Another ad called “Dream” features a girl born in El Salvador who came to the U.S. with her parents when she was 10 years old. She says she wants to become a pediatric nurse and join the U.S. Marine Corps but “living with the fear of being separated from my family, it’s something that I don’t want to go through.”

All the ads urge viewers to call their senators and urge congressional action now.

Labor unions have been some of the biggest proponents of a revamped system, in part because they hope that organizing immigrant workers can increase unions’ declining number of members. But unions are urging Congress to pass a bill that will provide a path to citizenship that’s unhindered by burdensome barriers.
